ALEXANDER W. HALL, OF NEW YORK, N. Y.

IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 55,491 dated June 12,1866.

To all whom it may concern Be it known that I, ALEXANDER W. HALL, of thecity, county, and State of New York, have invented a new and usefulImprovement in Ohurns; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, making a part of this specification, inwhich- Figure 1 is a vertical longitudinal section. Fig. 2 is a verticaltransverse section.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention consists in providing for the operation of the swingingor pendulum dasher of a churn by means of a pendulum-weight situatedoutside of the churn, whereby the power required to operate suchswinging dasher is much more conveniently and efficiently applied thanby any of the methods heretofore devised, and which in consequenceenables the churning operation to be performed with proportionallydiminished exertion on the part of the operator.

To enable others to understand the construction and operation of myinvention,1 will proceed to describe it with reference to the drawin gs.

A is an upright frame-work of any suitable form and situated upon a baseor bedplate, B. This frame-work,togetherwith its base,is preferably madeof wood, but may also be of any suitable material. Fixed uponeach end ofthe said frame-work is a horizontal transverse bar, 0, and formed in theupperside of each of these bars, at the center thereof, is formed ashallow notch, these'notches being represented in dotted lines in thedrawings.

1) is a horizontalbar which is placed longitudinally in the upper partof the frame-work A, being supported by the fixed transverse bars 0. Atthose points where this longitudinal bar D come in contact with the saidtransverse bars 0 it has its lower edge made sharp, as more clearlyshown in dotted lines in Fig.

, 2, in order to allow the said longitudinal bar D to be easily tiltedor rocked, as will be presently further explained. Projecting downwardfrom the under side of the bar D, and within the frame-Work A, are twohangers, E, to the lower ends of which is secured a box, F. This box maybe provided with a removable cover, and has placed in it a sufficientquantity of stones or other suitable heavy material to give it thedesired weight, the box F and hangers E constituting together apendulum-weight.

One end of the bar D projects out beyond the frame-work A, as shown ata.

G is the swinging or pendulum dasher of the churn. The upper end of thisdasher G is firmly secured to the end a of the bar D by any suitable orconvenient means, so that the dasher is thus suspended from the said enda.

The blade or lower end, I), of the dasher is situated Within the body Iof the churn, the two opposite sides of the said body being inclinedinward toward the top, as shown in Fig. 2, to correspond with theposition of thedasher at the ends of its lateral strokes or vibrations.

The operation of theinvention is as follows A swinging motion iscommunicated to the box F, or, in other words, to the pendulumweightformed by the said box and by the hangers E, either by pushing orpulling the box F with the foot or with the hands, orby any othersuitable means. This, of course, causes the bar D to rock upon the sharpedges thereof in contact with the upper sides of the bars G, ashereinbefore explained, and inasmuch as the dasher G is rigidly attachedto the outer end, a, of the said bar D, it follows that a swingin g orpendulum motion corresponding to that of the pendulum-weight F E iscommunicated to the said dasher, the blade thereof being moved from sideto side in the body I, and agitating or churning the cream containedtherein.

When desired the pendulum-weight E E may be connected by means of asuitable cord or string with the arm of a rocking-chair, and receive itsimpulse from the motion communicated to the chair by the occupantthereof, while by increasing or diminishing the contents of the box Fthe weight of the said pendulum may be proportioned to the quantity ofcream in the body I of the churn, and consequently to the resistance ofthe cream to the movements of the dasher G.

What I claim as new, and desire to secure by Letters Patent, is

Providing for the operation of the swinging dasher G by means of apendulum-weight applied outside of the churn and in connection with thesaid dasher, substantially as herein set forth.
